Chapter 1: Q2-28BSC (page 1)

In Exercises 21-28,determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is most appropriate.

Body Temperatures: Body temperatures (in degrees Fahrenheit) listed in Data Set 3 “Body Temperatures” in Appendix B.

Short Answer

Expert verified

The appropriate level of measurement for body temperatures measured in degrees Fahrenheit is aninterval.

Step by step solution

01

Given information

The body temperatures are recorded in degrees Fahrenheit.

02

Classification of data according to the level of measurement

The level of measurement is different for different types of data:

  • Nominal: This scale requires the values to label each given category under a variable. For example, labeling seasons as 1 for winter, 2 for summer, 3 for spring, and 4 for fall in no particular order.
  • Ordinal: This scale requires an increasing/decreasing order assigned to the values of the variable. For example, ranking of students in a class. The difference between each ranking is not fixed and does not indicate anything.
  • Interval: This scale requires that the values are equally spaced. For example, scores in an IQ test. Here, a zero score does not imply zero or no level of IQ.
  • Ratio: This scale requires the ratio of the values to exist and have a meaning. For example, the Kelvin scale of temperature measurement. Zero Kelvin means no heat, and 70 Kelvin is twice as hot as 35 Kelvin.
03

Identification of the appropriate scale

Since a temperature measured in degrees Fahrenheit is quantitative and equally spaced, but the absolute zero value does not mean “no heat”; so it is measured on aninterval scale.

In Exercises 17–20, refer to the sample of body temperatures (degrees Fahrenheit) in the table below. (The body temperatures are from a data set in Appendix B.)

Context of the Data: Refer to the table of body temperatures. Is there some meaningful way in which each body temperature recorded at 8 AM is matched with the 12 AM temperature?

Quantitative/categorical DataIdentify each of the following as quantitative data or categorical data.

a. The platelet counts in Data Set 1 “Body Data” in Appendix B.

b. The cigarette brands in Data Set 13 “Cigarette Contents” in Appendix B.

c. The colours of the M&M candies in Data Set 27 “M&M Weights” in Appendix B.

The complete set of all housing units equal to 132,802,859 present in the United States represents a parameter.

Statistical Significance and Practical Significance. In Exercises 13–16, determine whether the results appear to have statistical significance, and also determine whether the results appear to have practical significance.

Gender Selection In a study of the Gender Aide method of gender selection used to increase the likelihood of a baby being born a girl, 2000 users of the method gave birth to 980 boys and 1020 girls. There is about a 19% chance of getting that many girls if the method had no effect.

In Exercises 17–20, refer to the sample of body temperatures (degrees Fahrenheit) in the table below. (The body temperatures are from a data set in Appendix B.)

Source: The listed body temperatures were obtained from Dr. Steven Wasserman, Dr. Philip Mackowiak, and Dr. Myron Levine, who were researchers at the University of Maryland. Is the source of the data likely to be biased?
